[PATCH 0/2] staging: r8188eu: use ieee80211 helpers for subtype

[Martin Kaiser]

Use the ieee80211 helper functions in some places where the frame subtype
is checked.

[PATCH 1/2] staging: r8188eu: use subtype helpers in collect_bss_info

[Martin Kaiser]

Use the iee80211 helper functions to check the frame subtype in
collect_bss_info. Replace the call to the driver-specific
GetFrameSubType function.

[PATCH 2/2] staging: r8188eu: use subtype helper in rtw_check_bcn_info

[Martin Kaiser]

Use ieee80211_is_beacon to check the frame subtype in rtw_check_bcn_info.
Replace the call to the driver-specific GetFrameSubType function.
